Over the past half-decade, observations of gravitational waves (GWs)
have gone from being elusive to the routine. Since the first
detection of GWs in September 2015 [1]}, the
LIGO [2]} and Virgo [3]}
detectors have observed almost a hundred GW
signals [4]} from mergers of black holes
(BHs), neutron stars
(NSs) [5]}, [6]} and
their mixture [7]}. Placed alongside
independent confirmations of these detections, as well as, claims of new
ones [8]}, [9]}, [10]}, [11]}, [12]}, [13]},
these results have firmly established the field of GW astronomy.
